Description

Introduction: Body Mass Index (BMI) is of increasing interest to eye care practitioners. Associations have recently been proven between high BMI and several diseases of are affecting the eyes, including AMD, intracranial hypertension, optic disc cupping and glaucoma. The symptoms of dizziness and vertigo have also been associated with high BMI. However, to these authors’ knowledge, there has been no study performed comparing BMI to binocular function.

Methods: In this analytical-descriptive study, 119 randomly-selected young subjects had their BMI measured, along with refractive error, dissociated phoria, NPC, vergence ranges and facility, and stereopsis.

Results: In most situations, the subjects with the normal and overweight had better performance than other two groups. Also the worst performance was related to underweight subjects. The one-way ANOVA showed only statistically significant difference between mean of near point of convergence and vergence facility in different states of BMI.

Conclusion: Unlike most ocular diseases that are adversely affected by higher BMI values, most binocular vision skills are adversely affected by lower BMI values. The possible reasons for this are discussed.
